Advantages of the COMPUS TWIN over other types of compost toilet

  • The COMPUS TWIN vaults are designed for installation underground on level sites without the need for a basement or extensive ramp.
  • Urine separation means that the chamber does not require a drain. This makes the system suitable for sites with heavy clay soil or high groundwater.
  • The vaults are large enough to provide a level of biological and physical robustness that is not possible with smaller designs.
  • The design is mechanically simple with no moving parts except for a simple ventilation cowl.
  • The compost chamber forms the foundations and floor of the building. Foundations for the chamber are minimal.
  • The twin vault design allows for the removal of compost that is at least 1 year old.
  • The pedestal is designed to avoid fouling and to minimise cleaning.
  • The system requires no electricity, water or conventional sewage connection.
  • A COMPUS TWIN has a very low risk of smells in comparison with some other types of composting toilet. In fact we are confident that the risk of smells is less than with a WC due to (a) a ventilation system which operates from below the seat (b) urine separation (c) other design features.
